Questions & Answers

As answered by people managing PixFlip.app and Cert Decoder.

What's the story behind your product?

PixFlip.app's answer

Built out of frustration with existing image converters that upload your personal photos to their servers, show ads on every click, and limit free usage. PixFlip proves that modern browsers are powerful enough to handle image conversion entirely client-side.

Cert Decoder's answer:

I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.

Which are the primary technologies used for building your product?

PixFlip.app's answer

WebAssembly for high-quality image processing, modern web technologies for the interface. Everything runs in the browser — no server-side processing.

Cert Decoder's answer:

certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server

How would you describe the primary audience of your product?

PixFlip.app's answer

Anyone who needs to convert images quickly without installing software — photographers dealing with HEIC from iPhones, web developers optimizing images to WebP/AVIF, designers converting between formats, and privacy-conscious users who don't want to upload files to unknown servers.

Cert Decoder's answer:

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

Why should a person choose your product over its competitors?

PixFlip.app's answer

Privacy and speed. Most online converters upload your files to their servers — PixFlip doesn't. Conversion happens instantly in your browser, even offline. No registration, no file size queues, no watermarks. Unlimited batch conversion for free.

Cert Decoder's answer:

Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.

Who are some of the biggest customers of your product?

PixFlip.app's answer

  • Individual users converting iPhone HEIC photos
  • Web developers optimizing images for websites
  • Privacy-focused users who avoid cloud-based converters

Cert Decoder's answer:

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

What makes your product unique?

PixFlip.app's answer

100% browser-based conversion. Your files never leave your device — everything runs locally using WebAssembly. No upload, no server processing, no waiting in queues. Supports modern formats like AVIF and HEIC that most competitors don't handle client-side.

    Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
